Wait I see - it's making use of the breakdown voltage, correct? So if I stick say a 20 volt zener in there with the cathode toward the supply, it will drop somewhere around 20V across it? I guess my question then is, is this preferable to a resistor whose value is chosen to drop 20V? I ask this because I realize the compression effect large screen resistance is very real.
So did you finally use the zener to drop just the screen voltage?
